2. The wireless device of claim 1, wherein the one or more computer processors are further configured to cause the wireless device to determine the size of the preamble group in accordance with the RRC signaling.

3. The wireless device of claim 2, wherein the one or more computer processors are further configured to cause the wireless device to receive the preamble group from the base station when the wireless device is in an RRC_IDLE state or an RRC_INACTIVE state, wherein a first subset of preambles in the preamble group is associated with the RRC_IDLE state or the RRC_INACTIVE state.

4. The wireless device of claim 3, wherein a second subset of preambles in the preamble group is also associated with the RRC_IDLE state or the RRC_INACTIVE state.

5. The wireless device of claim 2, wherein the one or more computer processors are further configured to cause the wireless device to receive the preamble group from the base station when the wireless device is in an RRC_CONNECTED state, wherein a first subset of preambles in the preamble group is associated with the RRC_CONNECTED state.

6. The wireless device of claim 5, wherein a second number of preambles in the preamble group is also associated with the RRC_CONNECTED state.

7. The wireless device of claim 1, wherein the configuration of the PUSCH is one of a plurality of PUSCH configurations associated with the plurality of preamble groups, the plurality of PUSCH configurations further associated with a bandwidth part (BWP).

9. The non-transitory computer-readable storage medium of claim 8, wherein the computer instructions further cause the one or more computer processors to determine a size of the preamble group in accordance with the RRC signaling.

10. The non-transitory computer-readable storage medium of claim 9, wherein the computer instructions further cause the one or more computer processors to receive the preamble group from the base station, wherein a first number of preambles is associated with an RRC_IDLE state or an RRC_INACTIVE state.

11. The non-transitory computer-readable storage medium of claim 10, wherein a second number of preambles is associated with the RRC_IDLE state or the RRC_INACTIVE state.

12. The non-transitory computer-readable storage medium of claim 9, wherein the computer instructions further cause the one or more computer processors to receive the preamble group from the base station, wherein a first number of preambles is associated with an RRC_CONNECTED state.

13. The non-transitory computer-readable storage medium of claim 12, wherein a second number of preambles is associated with the RRC_CONNECTED state.

14. The non-transitory computer-readable storage medium of claim 8, wherein the preamble group is one of a plurality of preamble groups and the configuration of the PUSCH is one of a plurality of PUSCH configurations associated with the plurality of preamble groups, the plurality of PUSCH configurations further associated with a bandwidth part (BWP).

16. The method of claim 15, further comprising determining a size of the preamble group in accordance with the RRC signaling.

17. The method of claim 16, further comprising receiving, by the wireless device, the preamble group from the base station when the wireless device is in an RRC_IDLE state or an RRC_INACTIVE state, wherein a first number of preambles is associated with the RRC_IDLE state of the wireless device or the RRC_INACTIVE state of the wireless device.
